(S044)Reaction between solid MnO-SiO2-FeO oxide and solid Fe-Mn-Si alloy by heat treatment at 1473K

摘要

The reaction between Fe-Mn-Si alloy and MnO-SiO2-FeO oxide in the solid state has been investigated using the diffusion couple by some of the authors [1]. In their previous work, the diffusion couple was preheated at 1673K for 10min to ensure a good contact between the alloy and the oxide. However, to observe the solid state reaction by the heat treatment at 1473K, the influence of the heating at 1673K was not negligible. In this study, new method to melt the oxide at 1673K to produce diffusion couple was developed and the solid state reaction at 1473K was clarified by minimizing the influence of heating at 1673K.
